A nurse is preparing a child for a lumbar puncture. In which of the following positions should the child be placed for the procedure?

The correct position for a lumbar puncture in a child is the lateral position. This position allows for better visualization of the spine and easier access to the lumbar area. Placing the child in the lateral position helps to open up the intervertebral spaces and ensure proper alignment for the procedure. Prone position would not provide adequate access to the lumbar area. Semi-fowler and supine positions are not ideal for lumbar puncture as they do not allow for proper alignment of the spine.
